Rel-(1R,2R)-1,2-dimethylcyclopropane-1,2-dicarboxylic acid CAS 699-50-3

Description

The occurrence of Rel-(1R,2R)-1,2-dimethylcyclopropane-1,2-dicarboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Rel-(1R,2R)-1,2-dimethylcyclopropane-1,2-dicarboxylic acid (CAS 699-50-3), molecular formula C7H10O4 and molecular weight 158.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Rel-(1R,2R)-1,2-dimethylcyclopropane-1,2-dicarboxylic acid (C7H10O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
